the United States, respec n lug art Sho el-lands Albenv count N i'orh and i9 7 e 7 New You city, in the county of Kings end State of New lorlr, have inve. ted certain new and. usetul lniprovenn in .lhonorems, of which the following is at spcci lcation.

Our 'ivention relates to improvennnts in cylindrical. phonogreins or sound records lo talking machines and our principal objoc are to cheaply produce SW3d devices having the sound record on a shell of herd or indestructible materiel like celluloid, backed by a suitable material and provided with bcnring rings of relatively low oo-ellicient of expansion on the ends to engage the machine mandrel. o attain these objects in the the accompanying Figure 1 is a view of one of the bearing 5 the other bearing ring; Fig. 3 a sectional view of our improved backing with the rings inserted but without the record shell; Fig. l a like view with the rings secured to the backing which. has been surfaced to receive the shell; and Fig. 5 :1

View, partly in section of a complete phonograni on a machine .rnandrel.

Any suitable backing material, such as paper or cardboard is formed into tubes of proper length and forms the foundation of the phonogrem.

A metallic ring 2 having a bearing part 3 adapted to contact with the machine mendr'el and the turned over lip 4.- is pushed into one end of the backing tube 1. with the bean ing part 3 inside and the lip 4 outside. A 'second'ring 5 is made with the part 6 to contact with the inside of the tube 1, the inwardly extending bearing groove 7 adapted to contact with the machine mandrel and an u standing rebbet 8 provided with the rolle 'over edge 9 end is piecedv in the other end of the tube 1. The tube and rings are then subjected to the action or internal and the outer lip 4 end rabbet 8 lining rolled do r i into elinenient with the sul laceof the hlllll, 1

external rolling tools and the inner ends oi the bearing rings, the parts nnn'ked 3 and 3, are reamed into the tube as shown in Fig.

which at the some time is compressed to a stnndhrd size. This rolling or rooming; oi the e prevents withdrawal of the rings. The record shell. 1O carrying the sound record on its to is made by nnyoi the well known methods and is preferably of celluloid or like material provided with the integral end ring 11 which only carry any suitable inscription such as the numo ol the selection. This record shell is pushed onto the completed booking of l ig. d the lip 9 preventing cutting, the end of the ring oi the shelbconcouling the motel bearing ring 5, but not contacting with the machine mandrel. .llhe forward erui of the shell 10 covers the lip 4 and presents a nest eppeerlmce. By this con struction e record is produced which is precticully irnlestructiblc. As its only contact with the mandrel is two metal rings it is easily put on and removed. The record shell is supported throughout its entire extent endv the quality of the reproduction is improved thereby.

As there is no appreciable contraction of the 'metel rings and their internal bearing diznneters are accurately determined in man ui'octuring all records will occupy the some space on the mend el and consequently records for it given mandrel can be longer than if material having a high co-ellicicnt of cxonnsion is used to make the record.

"V are aware that metal bearing rings have been inserted in celluloid records or "honogrmns but such rings have heretofore cen attached directly to the celluloid.

We are also aware that backed celluloid phonogrems have heretofore been made and we do not claim such structures broadly.

1. A booking for phonogrums comprifng a tube of suitable nullerial adapted to re .eivc u record shell and independent, separated inc-- tnllic bearing rings in the ends of the tube adapted to contact with the machine mendrel.

2. A bucking lor phonogrnnis comprising a tub-v of suitable mot 'ol, a bearing ring ins de in one end he the outer cd c of the tube and its inner edge 'l'orwgd. into the l of the tube: and s i end or b tube he" mg its ne lip turned against contact-with the machine mandrel, a pro'ectrabbet alinin with the outer face 0 the tu e and a turne over outer edge.

3. A phonogram comprising a backing tube of suitable material, independent, separated bearing rings in each end adapted to contact with the machine mandrel and a shell of celluloid or like material having a sound record on its face in intimate contact with the outer face of the backing tube.

4. A phono%ram comfrisin g a backing tube of suitab e materia bearing rings in each end adapted to contact with the machine mandrel and a shell of celluloid or like material havin 'a sound record thereon on the outer face 0 the tube in intimate contact therewith, an integral inscription ring on one end of the shell adapted to conceal one of said bearing rings.

5. A backing for phonog'rams comprising a tube of suitable material adapted to receive a record shell and a metallic bearing ring in one end of said tube ada ted to contact with the machine mandrel tl ie backing adapted to contact with the mandrel at the other end.
